To all/whom t may concern.'

Be it known that I, CHARLES E. BLUE, of Wheeling, Ohio county, and Stateof West Virginia, have invented a new and useful Improvement in Machinesfor Gathering Glass, of which the following is a full, clear, and eXactdescription, reference being had to the accompanying drawings, formingFigure 1 is a vertical'section of one form of apparatus embodying myinvention; Fig. 2 is a plan view of the same partly broken away; andFig. 3 is an end elevation of a portion of the gearing.

My invention has relation to machines-for gathering glass, and isdesigned to provide a machine whereby the mechanical gathering of glassand its delivery to molds may be accomplished with accuracy andcertainty.

The precise nature 'of my invention will be best understoodl byreference to the accomone embodiment thereof, and which will now bedescribed, it being premised, how ever, that various changes may be madetherein by' those skilled vin the art, without departing from the spiritand-scope of my In these drawings, the numeral 2 designates aglass-melting tank or vessel, having an overhanging portion or dog-house3, formed with a discharge vopening 4 in its bottom wall. The dischargethrough this opening is controlled by a vertically movable stopper 5,which may be actuated in any as by the bell crank and operatinglever'connections 6, 7, 8, 9 and 10.

That portion of the discharge opening 4 which is nearest the interior ofthe tank is made lof smallerfdiameter than the exit portionthereof,"'and the Venlarged portion of this opening is extended througha discharging block 11, of refractory material which is vsecured to theunder side o-f the dog house and which is provided with a water jacket12, through which water may be circulated in any suitable manner.Secured to the lower end of the discharge block 1l by a hinge pin 13, orother suitable connection, is, a discharging ring 14, which is normallyheld in position by a removable pin or bolt 15.

16 is a rotary table or carrier which is arranged to turn on a centralstationary post measuring vessels or receptacles 18, so arrangedl thatwhen the table is rotated,these A receptacles will be brought insuccession beneath the orifice of the discharge ring 1.4.

These receptacles preferably have a narrow top opening dared downwardlyandclosed lat its lower end by a cup-shapedvalve 19,

which is hinged at 20, and. which is operated by suitable means so thatit'can be opened after the receptacle has received its dis-- v charge ofglass and has beenmcved into discharge position over a mold 21, intowhich f` the glass is to be delivered. v y l As-a convenient means forautomatically operating the valves 19, I provide each of them with ajointed operating rod 22, provided with a spring 23, which tends to pullthe valve open. The inner end of the rod` carries a wheel 24, whichtravels in cont-act with a statlona'rv cam surface 25, which extendsaround the central post 17. This cam surface at a point opposite theposition of the mold 21, has a recess 26, into which the rod is forcedby the spring 23, when the'discharging position is reached, thuspermitting thespring to, pull the valve-open, as

shown in full lines at the right-hand' side of Fig. 1, to therebydischarge the glass from the measuring vessel-into the mold below.

The opening at the top of each of the receptacles 18y ispreferablymadeoval or elongated in the direction of the rotation-I of the table.

The support 27 for the` table, together with the post-'17, is verticallyadjustable to the desired height, preferably by means of a rack 28, onthe support 27, which is engaged-by a pinion 29, operated byf a pawl(and ratchet 30, the ratchet being carried by. a lever 31.

The table may be rotated by any suitable means. In the drawings, I' haveshownit- 'as provided with a ,circular rack 32, whichis engaged by aspur wheel 33, driven through y l furnace. For the purpose ofvstopping.theV table positively at proper positi` v11sanyy suitable braking devicemay be employed, such as the spring-actuated dog 36, which is mounted onthe frame of the table and is arranged to engage notches 37 on thecentral post 17.

The operation is as follows: By depress-` ing the hand lever 10, whichcontrols the stopper 5, glass is allowed to start from the tank ormelting furnace and flows in a small hot stream through the contractedportion of the discharge opening 1,`and,thence into the enlargedwater-jacketed portion of said opening. In flowing through this enlargedportion of the discharge opening, the glass is cooled -to such an extentthat it will pass therethrough by a sliding action rather than by a How.-The purpose of this is three-fold. First, it enables the operation tobe started with glass suiiiciently hot to How freely through the smallentrance portion of the discharge orifice; second, it permits the glassto chill somewhat before it is discharged, so that by the time it getsto the mold-for use, it will not be so hot as tostick to the surfaceswith which it comes in contact; and third, it enables the cutting orsevering to occur with a column of glass at each operation instead of astream, so that an absolutely fixed quantity can 4be delivered out eachtime by means of the measuring vessel or receptacle. As each measuringvessel or receptacle is filled, the table or carrier is revolvedsutiiciently to bring another measuring vessel or receptacle intoposition, the solid plane 'portion of the table between the measuringvessels or receptacles acting to close the opening in the ring 14, untilsuch time as the measuring vessels or receptacles are brought intoproper relation to such opening. After each measuring vessel orreceptacle is filled, it is carried around to the mold 21, by thesuccessive rotations of the carrier and is discharged into the mold bythe openin of its bottom valve 19in ,the manner be ore described.

The machine herein described accomplishes with accuracy and certaintythe mechanical measuring of the glass delivered to the mold, thequantityof glass delivered to each mold being the same in all cases.

I do, not limit myself to the use of the particular form of movabletable or carrier which I have herein shown and described, as myinvention is independent thereof, and any suitable 'carrier may beemployed for transferring the glass delivered" from the tank or furnaceto the molds. Various other changes may also be made.
